Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

The structure of the East Australian Current is discussed, using the results of eight cruises between and The current is often U shaped, with a southward current near the continental shelf, and northward countercurrent further by: The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia.

The EAC provides both the western boundary of the. The East Australian Current (EAC) is the complex and highly energetic poleward western boundary current system of the South Pacific Subtropical Gyre. It is the dominant mechanism for the redistribution of heat between the ocean and atmosphere in the Australian region by transporting heat from the tropical Pacific Ocean to the midlatitude ocean and by: Here we investigate the jet structure of the East Australian Current (EAC), using observations from HF radars and moorings deployed at 30°S–31°S.

Meandering, core velocity, width, and eddy kinetic energy (EKE) are quantified from 4 years of hourly km resolution surface current maps (–), to obtain the most detailed representation of the surface EAC jet to by:   The East Australian Structure of the East Australian Current book. The East Australian Current flows south along the east coast of Australia from near Queensland's Fraser Island to Tasmania.

It is an important feature of the Tasman Sea between Australia and New Zealand, which. The Australian Army's structure from The following order of battle describes the Army's current organisational structure at the battalion and independent company / squadron level.

It does not take into account changes to units' structure and command arrangements associated. The East Australia Current is the western boundary current of the South Pacific subtropical gyre and is an important element of the heat tranport of the Pacific basin.

Abstract. This paper examines the model that the East Australian Current (EAC) is an important determinant of genetic structure for the direct developing intertidal snail Bedeva hanleyi.

Above latitude 33 o S on the east coast of Australia the EAC typically flows parallel to the shore in a southerly direction, whilst below 33 o S the direction of flow is predominantly by:   The East Australian Current With its source in the tropical Coral Sea, north-east of Queensland, the East Australian Current (EAC) moves a substantial volume of low-nutrient tropical water south down the Australian coastline towards the temperate regions, with ocean eddies peeling off into the Tasman Sea on the way.

Abstract We document the mean circulation of the East Australian Current (EAC) System, which is the major western boundary current in the southwest Pacific Ocean. A new high-resolution climatology of the region (CSIRO Atlas of Regional Seas, CARS) is used to produce regional fields of steric height and sections of geostrophic velocity.

The in situ dataset used in the current study consists of the Pacific Current Meter 3 (PCM3) array, which was a significant part of the Australian contribution to the World Ocean Circulation Experiment to study the variability of the East Australian Current (EAC), and was operational between September and March Area-preserving spectral analysis has been used to investigate the Cited by: 8.

The complex influences of the East Australian Current (EAC) and winds on the waters of the continental shelf were addressed with a ship survey, moored and drifting instruments, satellite images and wind and sea level measurements.

The study revealed intrusions of continental slope water reaching the inner continental shelf when the EAC was near the shelf edge and wind stress was near zero or Cited by: 5.

The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia. The EAC forms part of the western boundary of the South Pacific Gyre and the linking element between the Pacific and Indian Ocean gyres.

The EAC is similar to other western boundary currents and is dominated by a series of mesoscale eddies which. The East Australien Current - Continuous, or a Series of Eddies. Current atlases show an "East Australian Current" as a series of s from north of Brisbane to about Sydney (say 22° - 34°S).

The East Australian Current (EAC) is a complex and highly energetic western boundary system in the south-western Pacific off eastern Australia (Ridgway and Dunn ). Although its mean flow is relatively weak (Ridgway and Godfrey ) it is known to be a highly variable system with large mesoscale eddies dominating the flow (Bowen et al.
